EEXXEECCUUTTIIVVEE SSUUMMMMAARRYY

The City of Edmundston has identified inadequacies with various culverts on McRae Brook, a tributary of

the Madawaska River. The confluence of these watercourses is located adjacent to the culvert at 993

Victoria Street, within the municipal limits. In order to mitigate flooding at this location and stream

crossings upstream, the City has been replacing culverts on McRae Brook as part of a larger culvert

replacement project. Victoria Street is the final culvert to be upgraded as part of this program.

The proposed project involves the installation of six (6) 1200 mm round, concrete culverts beneath

Victoria Street, but slightly above the invert of an existing 1200 mm culvert. This will allow proper

passage of water from McRae Brook during periods of high flows. This will also allow the installation of

these culverts while maintaining fish passage through the original culvert. The culverts will be installed

by trenching and a traffic detour will be in place. Furthermore, city water and wastewater infrastructure

under Victoria Street will be removed and reinstated as part of the work.

Given the positive net effect on stream flows and the proposed mitigation measures, no adverse

environmental impacts are anticipated from the proposed project.

The name of the Undertaking is Victoria Street Culvert Upgrade.

22..22 BBAACCKKGGRROOUUNNDD

The City of Edmundston manages infrastructure projects within the City planning area, including culvert

installation and maintenance.

McRae Brook is a tributary of the Madawaska River north of Edmundston Centre, of which water levels

are partially impacted by the Madawaska Dam located approximately 4.9 kilometres downstream, near

Madawaska. Flooding of upstream properties has occurred above this location in the past, most recently

on the June 29, 2016.

The municipality is in the process of replacing undersized culverts on McRae Brook upstream of the

Victoria Street culvert, to prevent flow constrictions, flooding and road deterioration from erosion at these

sites. To complete the McRae Brook program, the Victoria Street crossing over McRae Brook must also

be upgraded to allow passage of water during periods of high flows and to prevent flooding at this

location.

The project involves the installation of additional culverts adjacent to the existing culvert, thereby

allowing fish passage to continue throughout the installation.

22..33 PPRROOJJEECCTT OOVVEERRVVIIEEWW

The City of Edmundston is proposing to upgrade the McRae Brook stream crossing at Victoria Street by

installing six (6) additional culverts adjacent to the existing culvert at a slightly higher invert.

The proposed culvert upgrade will be located within the footprint of the existing Victoria Street right-of-

way (ROW) and will also be located on two private properties. The City has met with these property

owners to discuss the project and associated encroachments. To correct existing stability and erosion

issues, the road base will also be widened within McRae Brook at the toe-of-slope by reconstructing the

embankment with competent fill and adding clean rip rap.

The culverts will be installed by trenching with excavators, according to the following sequence of work:

Installation of temporary water control works (TWCW), sediment control measures and detour

signage;

Electrofishing and removal of fish from work area;

Installation and commissioning of temporary watermain bypass line, relocated forcemain and sanitary

sewer bypass pumping;

Installation of culverts;

Placement of culvert pipe end protection;

Removal of TWCW;

Reinstallation of city service infrastructure noted above;

Completion of roadway, private property reinstatement and detour signage;

Removal of sediment control measures following stabilization of disturbed surfaces.

22..44 PPUURRPPOOSSEE//RRAATTIIOONNAALLEE//NNEEEEDD FFOORR TTHHEE UUNNDDEERRTTAAKKIINNGG

The McRae Brook culvert under Victoria Street is undersized and does not properly convey water to the

Madawaska River during periods of high flows (heavy precipitation events and spring freshet). The

required upgrading of upstream culverts, which are currently under construction, will increase the

flooding risk.

The installation of six additional culverts will reduce the risk of flooding during present and future high

flows in McRae Brook. The widening of the Victoria Street toe-of-slope will correct road stability

concerns at this site, preventing erosion of the road subsurface and thereby preventing water quality issues

in the future.

22..55 PPRROOJJEECCTT LLOOCCAATTIIOONN

The proposed culvert upgrade is located at the Victoria Street crossing of McRae Brook, at civic address

993 Victoria Street. The subject property, Service New Brunswick PID No. 00000003, is a provincial

road right-of-way (ROW) under the management of the City of Edmundston. Parcel Nos. 35297761 and

35186584 are located immediately adjacent to the stream crossing and have been affected by flooding in

the past (refer to project location figure 1.0).

The site is located within the City of Edmundston city limits, and is therefore within the mandate of the

City of Edmundston’s Director of Development and Engineering.

The centre of the proposed project is geo-referenced at LAT 47O, 24’, 11.29” N, LONG 68O, 21’, 13.16”

Figure 1: Project Location

The overall footprint of the project development area is approximately 2,000 square metres, located at the

confluence of McRae Brook and the Madawaska River. The site is bordered to the east by forested

parcels and to the west by the Madawaska River. North and south of the site is primarily residential

development along Victoria Street.

No regulated wetlands are located within, or adjacent to, the project footprint.

22..66 SSIITTIINNGG CCOONNSSIIDDEERRAATTIIOONNSS

The project site is a necessity due to existing conditions in McRae Brook and the Madawaska River.

Alternative sites were not considered as relocating the project is not possible.

22..77 PPHHYYSSIICCAALL CCOOMMPPOONNEENNTTSS AANNDD DDIIMMEENNSSIIOONNSS OOFF TTHHEE UUNNDDEERRTTAAKKIINNGG

The drainage basin upstream of Victoria Street has an approximate area of 247 ha, an approximate

average slope of 6% and an approximate weighted curve number of 83. The estimated peak flow

generated by a 100 year +20% storm is 15.8 m3/s.



Figure 2: Project Area Overview

The proposed culverts consist of six (6) circular 1200 mm ø concrete conduits having a length of 34.2

metres and a slope of 2.05% each. Scour protection will be achieved by placing R-100 riprap at pipe

inlets and outlets, as well as on the embankments, and a cast-in-place concrete headwall will be installed

at the inlet and outlet ends of the culverts. Removable grate will be anchored to the cast-in-place

headwalls to ensure that beavers do not create blockages at or within the culverts, as this has been a

problem in the past. Backfilling of the pipe surround area will be achieved by placing unshrinkable fill

between the conduits in order to prevent consolidation of material due to the weight of overlying material.

Tension bar assemblies will be installed, and will span the first three pipe joints on all inlets and outlets.

An existing partially submerged circular 1200 mm ø concrete conduit having a length of 21.8 metres and

a slope of -0.20% will remain in place during and following the installation of the new conduits in order

to provide continued water conveyance and fish passage. Fish weirs are not present in the existing

culvert, as it is at least partially submerged at all times; the inlet and outlet invert elevations are 142.79

metres and 143.18 metres respectively, and the normal operating water levels vary between

approximately 143.30 metres and 143.70 metres. A bathymetric survey was carried out on April 28,

2017, and the water elevation was measured at approximately 143.70 metres. The condition of the

existing culvert was evaluated by CCTV inspection by the City of Edmundston, and was deemed to be in

good condition.

Construction of the Victoria Street Culvert Upgrade is scheduled to begin as soon as regulatory approval

(Certificate of Determination) is granted. The tendering process has already been completed, the contract

has been awarded, and the necessary materials have been acquired.

The construction is anticipated to be completed in 6 weeks, provided that there are no significant weather-

related delays.

22..99 RREEGGUULLAATTOORRYY AAPPPPRROOVVAALLSS

The Province of New Brunswick’s Department of Environment and Local Government (DELG) regulates

any alteration within 30m of a watercourse or wetland, including the installation of culverts, through the

Watercourse and Wetland Alteration Regulation and permitting process.

In instances where a culvert may also impact an item under Schedule A of the Environmental Impact

Assessment (EIA) Regulation, the project must be registered for an Environmental Impact Assessment

(EIA) as well as obtain WAWA permit, in addition to any municipal permits and approvals. In this

instance, the Department of Environment and Local Government has identified the subject site section of

Victoria Street as a causeway as per Item i) of Schedule A “all causeways and multiple-span bridges”,

and the installation of six additional culverts as a significant modification to a causeway.



22..1100 AALLTTEERRNNAATTIIVVEE DDEESSIIGGNN CCOONNSSIIDDEERRAATTIIOONNSS

The 6-culvert design was chosen after assessing alternative options for this site:

Null Alternative: The null alternative is not an option; if the current situation at Victoria Street is not

corrected, the area will experience flooding at an even greater scale than has previously occurred. This

could result in property damage, damages to private structures, and to Victoria Street.

Bridge Option: A bridge option was reviewed; however, this would have required a complete excavation

of the existing section of Victoria Street, the rerouting of McRae Brook and installation of significant

water control structures in McRae Brook and Madawaska River, the suspension and protection of

municipal utilities to the underside of the bridge, the excavation of virgin ground and the installation of

significant bridge abutment structures on both sides of the watercourse. Based on these factors, the

increased construction time, the potential for environmental impacts, and the prohibitive cost, this option

was discarded.

Box Culvert Option: A concrete box culvert option was also assessed. The installation of a box culvert

would require the use of a crane, requiring the temporary removal of overhead power lines and

subsequent suspension of power services. This option was deemed to be more cost prohibitive than the

proposed round culvert upgrade, and not feasible due to the issues associated with the overhead power

lines. As such, this option was discarded.

Preferred Option: The proposed installation of multiple culverts was chosen due to the ease of installation

(using standard equipment), the short timeline required for project completion, the avoidance of removing

overhead power lines, and the least prohibitive cost.

3.1 PHYSICAL AND NATURAL FEATURES

General

The subject site consists of the Victoria Street right-of-way in Edmundston, Madawaska County, New

Brunswick where it crosses McRae Brook. The confluence of McRae Brook and the Madawaska River is

adjacent to (west of) Victoria Street at this location.

McRae Brook is approximately 15 metres in width upstream of the crossing and approximately 45 metres

in width downstream; however, it should be noted that this width is due to the impoundment of the

downstream Madawaska Dam, and narrows significantly approximately 150m upstream.

Geology

Geology in the area is not applicable to this project. The project will take place within the constructed

(man-made) sub-layers of Victoria Street.

Topography

The portion of Victoria Street at the project site is flat, sloping to either side (east and west) at a 1:1 slope.

McRae Brook has relatively gentle slopes on either side at this location, due in part to the residences on

either side.

Surface Water

According to GeoNB Map Viewer, there are no regulated wetlands within the proposed project footprint.

There is one (1) Provincially Significant Wetland (PSW), Boucher Lake, approximately 1 km upstream

and east of the site; however, this is not anticipated to be impacted by the project.

The subject site is located adjacent to the confluence of Madawaska River and McRae Brook; however,

the water level at the subject site is impacted by the existing Madawaska Dam downstream at Queen

Street.

The confluence of the Madawaska River and Saint John River is approximately 5.5 kilometres south of

the subject site.

The McRae Brook drainage basin upstream of Victoria Street has an approximate area of 247 ha, an

approximate average slope of 6% and an approximate weighted curve number of 83. The estimated peak

flow generated by a 100 year +20% storm is 15.8 m3/s.



Figure 6: Site Location and Wetland Mapping (GeoNB Map View).

Groundwater

Nearby residences are serviced by the City of Edmundston’s water and sewer services.

Vegetation

The site location contains common vegetation species at the edge of Victoria Street, primarily speckled

alder (Alnus incana) and willow (Salix spp), immature white pine (Pinus strobus), trembling aspen

(Populus tremuloides), balsam fir (Abies balsamea), red maple (Acer rubrum), white birch (Betula

papyrifera) and mountain ash (Sorbus aucuparia). Only the vegetation within the footprint of the culvert

installations within the ROW will be removed for the purpose of the project.

Wildlife and Wildlife Habitat

The subject site is located in an urban area within the City of Edmundston and is not considered suitable

habitat for most common wildlife species.

Based on previous culvert installations, McRae Brook is known to contain Creek Chub (Semotilus

atromaculatus), White Sucker (Catostomus commersoni) and Ninespine Stickleback (Pungitius

pungitius).



Migratory Birds

According to the Canadian Wildlife Service, “Under Section 6 of the Migratory Birds Regulations

(MBR), no person shall disturb, destroy or take a nest or egg of a migratory bird; or to be in possession of

a live migratory bird, or its carcass, skin, nest or egg, except under authority of a permit. It is important to

note that under the current MBR, no permits can be issued for the incidental take of migratory birds

caused by development projects or other economic activities. Furthermore, Section 5.1 of the MBCA

describes prohibitions related to deposit of substances harmful to migratory birds:

“5.1 (1) No person or vessel shall deposit a substance that is harmful to migratory birds, or permit such a

substance to be deposited, in waters or an area frequented by migratory birds or in a place from which the

substance may enter such waters or such an area.

(2) No person or vessel shall deposit a substance or permit a substance to be deposited in any place if the

substance, in combination with one or more substances, results in a substance — in waters or an area

frequented by migratory birds or in a place from which it may enter such waters or such an area — that is

harmful to migratory birds.”

The City of Edmundston recognizes that it is the responsibility of the proponent to ensure that activities

comply with the MBCA and regulations.

The site is anticipated to contain typical, common bird species for an urban area; however, the project is

not anticipated to impact migratory birds.

Species at Risk

Canada’s Species at Risk Act (SARA) is one of three major components in the Government of Canada

Strategy for the Protection of Species at Risk. It is designed as a key tool for the conservation and

protection of Canada’s biological diversity and fulfils an important commitment under the United Nations

Convention on Biological Diversity. New Brunswick also has a Species at Risk Act, which complements

the federal Act.

The purpose of SARA is to:

A. Prevent wildlife species from becoming extinct or extirpated (lost from the wild in Canada);

B. Help in the recovery of extirpated, endangered or threatened species; and

C. Ensure that species of special concern do not become endangered or threatened.

The project is not anticipated to impact species at risk.

Environmentally Significant Areas

A review of the Nature Trust NB Environmentally Significant Area (ESA) database found several ESAs

within a 5 km radius of the subject site; however, the closest ESA sites are:

ESA #214 Etang McRae:

This small bog pond of 1.6 hectare is the focus of much attention among local naturalists. It serves as a

good representative of bog habitat, which is rare in this part of the province. It is also home to several

plant species that are uncommon or rare in the northern part of the province. These include: Small



Cranberry (Vaccinium oxycoccus); American Watershield (Brasenia schreberi); Water-arum (Calla

palustris); Common Duckweed (Lemna minor); Yellow Loosestrife (Lysimachia terrestris). At least 68

species of birds have been observed here.

This wetland is located approximately 1 km upstream of the subject site and is not anticipated to be

impacted by the project.

ESA #218 Madawaska River Sandspit: This ESA is located on the west (opposite) bank of the

Madawaska River. Known as good migratory waterfowl habitat. Ice scouring and flooding are

probably the main natural disturbances. This site is suitable for plants associated with gravel strands.

The rare plants Muhlenbergia richardsonis and Schizachyrium scoparium (Michx.) Nash, have been

reported near here at Clair on a river strand. Another rare plant to look for at this site is Potamogeton

pectinatus.

This site is not anticipated to be impacted by the project.

Figure 7: Environmentally Significant Area Locations

Archaeological Resources

Based on the subject site (a man-made road structure), no archaeological resources are anticipated to be

encountered or impacted by the project.

ESA 218

ESA 214 Project Site



Land Use

The project is proposed on land owned by the City of Edmundston which serves as an existing road

ROW, as well as on two parcels of private land. No Land Gazette flags were identified within the subject

site or adjacent properties.

No land use issues or conflicts are anticipated from the project, as the private land owners on which the

work will take place have been contacted and are in agreement with the proposed work.

Transportation

The subject site is an existing municipal roadway, necessary for efficient traffic flow in the area. The

work will require closure of the road and a traffic detour will be implemented for the duration of the

project. The NB Department of Transportation and Infrastructure is aware of this requirement.



44.. EENNVVIIRROONNMMEENNTTAALL AASSSSEESSSSMMEENNTT OOFF PPOOTTEENNTTIIAALL IIMMPPAACCTTSS

Based on the project description and the existing environment, the following Valued Environmental

Components (VECs) were identified for the EIA:

a) Surface Water Quality

b) Fish Habitat

c) Transportation

A qualitative rating system was used to evaluate the potential for interactions between the project and the

environment. A rating was given to each Valued Environmental Component (VEC) based on a rating

system according to professional judgment and experience of the consultant.

0 = No interaction anticipated.

1 = Interaction occurs; however, it is unlikely to result in a significant environmental effect even

without mitigation, or it is unlikely to be significant because of mitigation measures.

2 = Interaction could potentially result in an environmental effect.

Where there is a potential for project-VEC interaction (ratings of 1 or 2), further discussion is provided in

the following sections. For issues where there is limited interaction (ratings 0 or 1), a rationale is

provided and the issue is not discussed further in the present report. Potential project-environment

interactions are presented in Table 8.

The potential VECs that have a rating of zero for all activities indicate that the particular VEC is not

present within or in proximity to the project’s footprint. The rationales for excluding these VECs from

further assessment are discussed in the following sections.

Significance of potential environmental effects is also evaluated in this section, based on a consideration

of four (4) characteristics of the project-VEC interaction:

1. Likelihood: What is the likelihood of the impact on the VEC?

2. Spatial scale: How large an area/how many of the VEC will be impacted?

3. Duration of impact: How long will the VEC be impacted? and



4. Mitigation: What mitigation measures can be employed to minimize the impact, and how

efficient?

4.1 SURFACE WATER

The proposed project will be completed within the footprint of the McRae Brook/Madawaska River

confluence.

Existing Conditions:

At present, the Victoria Street culvert is partially to completely submerged and inadequate (undersized)

for conveying increased water flows in McRae Brook during periods of high water flows.

The water level immediately upstream of the site is affected by the Madawaska Dam, located

approximately 5 km downstream. However, during periods of high flows, the upstream properties’ water

levels increase significantly and flooding occurs.

The proponent has applied for a WAWA permit to undertake work within 30 m of a watercourse.

Furthermore, the project is the final culvert in a larger program of culvert replacements on McRae Brook

designed to prevent localized flooding and road erosion created from undersized culverts.

Project-VEC Interactions, Potential Environmental Effects:

Environmental Impact 1: Excavation may result in sediments reaching the watercourse.

The installation of the six (6) culverts will be conducted by trenching, using an excavator from road level.

This may result in sediments from the road sub-compacted layers reaching the watercourse during

excavation, which may adversely impact water quality if not properly mitigated.

Recommended Mitigation 1:

Work will take place “in the dry”;

Work will take place during the summer low-flow period;

In the event of a sustained, heavy precipitation period, work will be delayed until conditions return to

favourable;

Material and equipment will be stockpiled outside of the 30 m watercourse buffer where practical;

Equipment will be refueled outside of the 30 m watercourse buffer zone;

All site work, excavation, culvert installation, backfilling, placement of rip-rap, etc. will be completed

according to a signed and stamped engineer’s design – and as per the NB WAWA Technical

Guidelines. This will include, but not be limited to, the use of clean, non-toxic materials and standard

sediment and erosion controls such as the placement of geotextile fabric fences.

Significance of Potential Impacts

Based on the temporary nature of the project, the work is anticipated to take place “in the dry”, and the

use of the mitigation measures noted above, water quality impacts are considered unlikely and not

significant.



4.2 FISH HABITAT

The proposed project will be completed within the footprint of the McRae Brook/Madawaska River

confluence.

Existing Conditions:

Although a fish habitat survey has not been completed for this project, it can reasonably be assumed that

McRae Brook and Madawaska River contain fish and fish habitat. Electrofishing previously conducted

on McRae Brook identified three species: Creek Chub, White Sucker and Ninespine Stickleback.

Project-VEC Interactions, Potential Environmental Effects:

Environmental Impact 1: Placement of rip rap along the toe-of-slope may impact approximately 250

square metres of fish habitat.

Environmental Impact 2: The excavation of Victoria Street may result in increased sedimentation in

McRae Brook and the Madawaska River, which may impact fish habitat.

Environmental Impact 3: The project may impede fish passage during the 6-week construction period.


The area to be impacted will be limited to the smallest area necessary to strengthen the roadway from

future flooding, thereby reducing the potential for future excavations within the McRae Brook

watercourse. The work area will be electrofished and individual fish will be removed/released outside of

the work site. Fish species identified will be recorded and compiled.


Standard erosion and sediment controls will be implemented throughout the construction process, based

on a stamped engineer’s design and as per the WAWA Technical Guidelines.


The excavation will be conducted from street level, adjacent to the existing culvert, and will not require

excavation of the watercourse, nor alter or impact the existing culvert, which will be maintained in place

for fish passage during construction.

Significance of Potential Impacts

Based on the minimal area of fish habitat potentially impacted and the mitigation measures to be

employed during construction, potential impacts to fish habitat are considered unlikely and not

significant.

The construction of the proposed project will correct an undersized culvert, which if not completed will

be creating impacts upstream on McRae Brook, namely flooding of the riparian area and possible erosion

of infrastructure during high flows.

Based on the minimal potential adverse environmental impacts, the existing project footprint and the

anticipated restorative benefits of the project, no cumulative effects assessment was required for this

project.

Re: Bathymetric Survey of the Madawaska River near

the culvert replacement location on Victoria Street

Dear Jeff:

As requested, we surveyed the bathymetry of the small cove on the edge

Madawaska River (on the Southwest side of Victoria Street), on April 25, 2017. We also

surveyed the small water body on the opposite side of the culvert. Figure 1 shows where

these sites are located.

1. Methodology

Bottom depths were determined using a manned boat equipped with a GPS and a 200 kHz

echo sounder. The shoreline was traced based on aerial photography. The elevation of

the water level was surveyed using a Total Station, and referenced to the geodetic

benchmark provided by you (#26294, X: 2360632.827m, Y: 7601650.221m, Z: 150.011m)
